Detailed overview: EcoFlow River 3 portable power station
The EcoFlow River 3 is the brand's smallest portable power station, designed for anyone who wants a real energy reserve without the bulk. In a flat 3.5 kg body, it combines a 245 Wh LiFePO4 battery and a 300 W output (up to 600 W peak with X-Boost), enough to power most everyday mobile devices: phones, a tablet, a laptop, lighting, a drone, a camera or a small fan.
Its technical novelty, X-GaN technology, doubles runtime on devices under 100 W, very common in camping and mobile work. For connectivity, it offers 2 AC outlets, 1 USB-C 100 W port, 2 USB-A ports and a 12 V car outlet (126 W), enough to charge several devices at once. Recharging is a strong point: about 1 hour for a full charge from the mains thanks to X-Stream fast charging, plus a solar input up to 110 W to refuel at camp.
The River 3 also includes an inverter (UPS) function that switches to battery in about 10 ms during an outage, perfect to protect an internet router, a camera or a computer during micro-outages. Its LFP chemistry, rated for 3000 cycles (about 10 years of regular use), its IP54 battery protection and its fireproof shell make it a rugged, durable companion. It runs at under 30 dB, goes completely unnoticed and is controlled from the EcoFlow app via Bluetooth.
Its only real limit is its capacity: 245 Wh suit light devices and short durations, and unlike the River 3 Plus, the River 3 is not expandable with an add-on battery. But for anyone after a first compact, fast-charging and durable power station, it offers a remarkable footprint-to-versatility ratio.

What is this power station best for?

Camping & Tent Ideal
Ultra-compact (3.5 kg) and quiet (30 dB), the River 3 is the ideal station for the light-packing camper: its 245 Wh cover lighting, charging phones, a tablet, a camera and topping up a small fan for an evening or a night, and its X-GaN technology doubles runtime on devices under 100 W. Its 300 W (600 W X-Boost) run an electric pump or a small appliance, and its near-silent operation preserves the calm of the campsite. Rechargeable to 100 % in one hour from the mains and up to 110 W in solar, it refuels at camp on a sunny day. The LiFePO4 chemistry (3000 cycles) lasts many seasons, and its flat shape slips into a backpack or a boot without getting in the way. For a light bivouac or a weekend for two, it is an energy reserve you forget you are carrying.
-
Road trip & Car Suitable
On a road trip, the River 3 makes itself tiny and recharges fast: at 3.5 kg it fits in any nook of the cabin and recharges cameras, drones, a laptop and phones between stops, without draining the vehicle battery. Its full recharge in one hour lets you set off charged after a short break, and its solar input up to 110 W extends autonomy on long days. Quiet (30 dB), it goes unnoticed. Its 245 Wh reserve it for light devices; to keep a cooler running for several days, a larger station will be preferable.
-
Photo & Video Suitable
On a photo or video shoot, the River 3 makes a discreet, practical backup rig: its 245 Wh recharge a good series of mirrorless camera batteries, drone packs and mics between takes, and its one-hour recharge tops it up fast. Its 100 W USB-C powers a laptop or fast-charges a second device, and its 300 W suffice for a small LED fill panel. At 3.5 kg and 30 dB, it disappears into the camera bag and follows a light crew unnoticed, even on sensitive sound recordings.
-
Remote work Suitable
For a mobile work session, the River 3 powers and protects the essentials: its UPS function switches over in about 10 ms and shields the laptop and router during a micro-outage, while its 100 W USB-C fast-charges a laptop. Its 245 Wh ensure several hours of connectivity for a light setup, and its X-GaN technology stretches runtime on low-draw devices. Compact (3.5 kg), quiet (30 dB) and recharged in one hour, it travels effortlessly from a cafe to a coworking space. For a full day with an external screen and peripherals, aim for a higher capacity.
-
Health & CPAP Suitable
For a CPAP device on the move, the River 3 is a compact safety net: its 245 Wh generally cover a night of therapy without heated humidifier, and its UPS switches over in about 10 ms during an outage, without waking you. Quiet (30 dB), it slips onto the bedside without disturbing sleep, and its full recharge in one hour tops it up very fast each day. Its light weight (3.5 kg) makes it an ideal travel companion. Check your device's real consumption: with heated humidification, runtime will be shorter.
-
Home & Power cuts Backup only
As a backup during an outage, the River 3 takes over instantly thanks to its UPS function (switchover in about 10 ms): it keeps the internet router and a light point running without interruption. Its 245 Wh help out during short outages and for essential devices only; it does not replace a larger-capacity station to cover a home for several hours.

Compatible solar panels
A selection of photovoltaic panels that suit this station's solar input (up to 30V / 110W), best match first.
Comparison
Under 300 euros, the EcoFlow River 3 takes on the compact power stations of about 250 Wh, often compared through searches like "River 3 vs Bluetti EB3A" or "River 3 vs Anker C300". Here is how it stacks up against three alternatives: the more powerful Bluetti EB3A, the very light Jackery Explorer 300 Plus, and the same-capacity Anker SOLIX C300.
| Criterion | EcoFlow River 3 | Bluetti EB3A | Jackery Explorer 300 Plus | Anker SOLIX C300 |
|---|---|---|---|---|
| Capacity | 245 Wh | 268 Wh | 288 Wh | 288 Wh |
| Continuous / peak power | 300 W / 600 W | 600 W / 1200 W | 300 W / 600 W | 300 W / 600 W |
| Mains recharge 0-100 % | ≈ 1 h | ≈ 1 h 30 | ≈ 2 h | ≈ 2 h |
| Weight | 3.5 kg | ≈ 4.6 kg | ≈ 3.75 kg | ≈ 4.1 kg |
| Observed price | ≈ 259 € | ≈ 259 € | ≈ 299 € | ≈ 279 € |
In short, the River 3 is the lightest and fastest to recharge of the group (1 h versus 1 h 30 to 2 h), with an inverter function and X-GaN technology that stretches runtime on small devices. The Bluetti EB3A wins on raw power (600 W continuous), useful for a small kettle, and the Jackery 300 Plus shaves off a few grams. For portability and charging speed, the River 3 remains the best compromise at this price.

Our tester's review: Christophe Delpuech
We slipped the River 3 into a backpack to see how far EcoFlow's smallest station goes, and it surprises. At 3.5 kg and barely thicker than a big book, you really take it everywhere: on a day of hiking photography it recharged two camera bodies, a drone and our phones without flinching. The one-hour recharge is the model's real luxury, you top it up in the time it takes to have a coffee. As backup at home, its inverter function kept the router and a camera running without the slightest flicker during a micro-outage. The silence is total, you forget it under the tent. Two owned limits: 245 Wh remains a small reserve, best kept for light devices, and unlike the River 3 Plus it is not expandable, which you must anticipate if needs grow. For a first compact, fast and LFP-durable mobile station, it offers a footprint-to-service ratio that is hard to beat.
